Slough council has published the order for a 20mph limit on 35 roads in Colnbrook and Poyle, plus speed humps on Horton Road. Objections close 8 October.
A 20mph speed limit is a step closer for 35 roads in Colnbrook and Poyle. Slough Borough Council published the proposed order on 22 September, and objections must reach it before 9 October.
A second notice, dated 25 September, proposes speed cushions and a speed table on Horton Road. Comments on that close on 16 October.
Colnbrook and Poyle sit at the eastern edge of the borough, about three and a half miles east of the town centre, between the M4, the M25 and Heathrow.
Which roads are in the 20mph order
The proposed order is the Colnbrook and Poyle 20mph Speed Limit Order 2026, Order 19 of 2026. It was signed on 18 September by Matthew Hooper, the council’s Director of Environment and Highways.
It names these roads for their entire length:
| Village streets | Residential roads and closes |
|---|---|
| High Street, Colnbrook | Popes Close, Moreland Avenue, Moreland Close |
| Bridge Street | Drift Way, Beacon Court, Brookside Road |
| Park Street | Willow Close, Rayner Close, Crown Close |
| Vicarage Way | Coleridge Crescent, Hunstanton Close, St Thomas Walk |
| Mill Street | Aintree Close, Winchester Close, Raymond Close |
| Albany Park | Rodney Way, Laurel Close, Fawsley Close |
| Tall Trees | Myrtle Close, The Hawthorns, Daventry Close |
| Dawley Ride | Polar Close, Sherborne Close, Ingleside Road, Meadowbrook Close |
Two main roads are included only in part:
- London Road, from 5 metres east of its junction with Crown Meadow to its junction with Horton Road
- Bath Road, from its junction with Albany Park to a point 80 metres east of its junction with Meadowbrook Close
The order’s schedule adds “Road” to four names, printing “Mill Street Road”, “Albany Park Road”, “Tall Trees Road” and “Dawley Ride Road”. The streets themselves are Mill Street, Albany Park, Tall Trees and Dawley Ride, and we have used those names.
The council gives three reasons in its statement:
- to bring existing limits in line with current standards and government guidance
- to avoid danger to people and other traffic
- to preserve or improve the amenity of the area
If it is made, the order takes effect on the day the council first publishes a notice saying so.
Speed humps on Horton Road
Horton Road stays at 30mph. Instead the council wants to slow traffic on its residential stretch, heading from Popes Close towards the Bath Road and Colnbrook High Street.
The Highways Act notice proposes:
- two sets of speed cushions, the first 137 metres east of the Popes Close junction and the second 214 metres east of it
- one speed table, 12 metres long, 6 metres wide from kerb to kerb and 75mm high
The cushions are up to 75mm high and 1.6 metres wide, so buses and larger vehicles can straddle them. The notice does not say exactly where on Horton Road the speed table goes. The plan showing it can be inspected at Observatory House or at The Curve.
The reason is the council’s own speed survey. It found that 85% of vehicles on Horton Road were travelling faster than the 30mph limit, according to the council’s scheme page.
The consultation version last year also promised rumble strips and vehicle-activated signs. Those are not covered by the humps notice, and the council has not said whether they are still planned.
How the scheme got here
Residents have pushed for this since 2022. The council’s decision report says the Colnbrook Community Association, local councillors and the parish council had been asking the transport team for a 20mph scheme since then.
The first idea was 20mph on every residential road in Colnbrook and Poyle. That was costed at £76,000, and neither the council nor the community association nor the parish council could fund it at the time. The area was cut back, working with Colnbrook with Poyle Parish Council, to the 35 roads now in the order.
The council consulted from 8 to 28 November 2025 and received 31 responses. Its report says more than half were supportive or strongly supportive. Many others backed a 20mph limit in principle but wanted enforcement or physical traffic calming to go with it.
The themes, as the council counted them:
| Theme | Comments |
|---|---|
| Enforcement and policing | 15 |
| Cut-through and rat-running traffic | 13 |
| Whether 20mph limits work | 12 |
| Car racers and antisocial driving | 11 |
| Schools and vulnerable road users | 10 |
| Engineering measures and design | 9 |
| Support for the scheme | 8 |
| The consultation process | 7 |
| Heritage and the conservation area | 6 |
On enforcement, the council’s answer is that speed limits are enforced by Thames Valley Police, and that it works with the force on targeted enforcement where it can. On heritage, it says it will keep signs to a minimum and place them carefully in the conservation area.
Pat Hayes, the executive director, approved the scheme on 28 January 2026. The report says it is paid for from a Department for Transport grant. It does not give the cost of the reduced scheme.
What it means for you
If you live in Colnbrook or Poyle, or drive through, the practical points are these.
- To object to the 20mph limit, write to Matthew Hooper, Director of Environment and Highways, Slough Borough Council, Observatory House, 25 Windsor Road, Slough SL1 2EL. Quote “Colnbrook and Poyle 20mph speed limit Order 2026 (Order 19 of 2026)” and give your grounds. It must arrive before 9 October, so by Thursday 8 October.
- To comment on the Horton Road humps, email TransportPlanning@slough.gov.uk with “COLNBROOK AND POYLE - Enquiry” in the subject, or write to the same address. The deadline is 16 October.
- Objections are what count at this stage. The council’s scheme page says that if there are no objections, it will bring the scheme in under a permanent order. A written objection with grounds is what the council has to consider before it decides.
- Nothing changes on the road until the council publishes a notice that the order has been made.
The same notice lists the council’s reasons and a plan, which you can inspect on its permanent orders page. When we checked on 28 September, that page did not yet carry this order. The Public Notice Portal copy linked above is the full published text.
